Diagnosis. Elytron entirely dark-brown ( Figs. 58 ). Male with eye small (half as wide as distance between eyes) ( Fig. 62 ); pygidium almost 4x sternum VIII greatest length, with lateral margins convergent posteriad, posterior margin with median third rounded, ventral keels convergent posteriad, sinuose in lateral view ( Figs. 66–68 ); sternum IX 3x longer than aedeagus, arms lacking stout subapical setae, convergent posteriad, apices truncate, right arm slightly longer ( Figs. 69–71 ); paramere slightly curved inwards, apex rounded ( Figs. 72, 74 ).

Description. Male. Colour pattern overall dark brown, except by the yellow spots of rudimentary larval lanterns on sternum VIII ( Figs. 58, 68 ). Pronotum with distance between posterior angles shorter than pronotal greatest width, narrower than distance between elytral humeri, posterior angles obtuse ( Fig. 64 ). Hypomeron ventrally rounded ( Fig. 63 ). Eye small (half as wide as distance between eyes) ( Fig. 62 ), shorter than head ( Fig. 63 ); antennomere IV 2x longer than wide ( Fig. 61 ); pygidium almost 4x longer than sternum VIII greatest length, with lateral margins convergent posteriad, posterior margin with median third rounded, ventral keels convergent posteriad, sinuose in lateral view ( Figs. 66–68 ); sternum VIII strongly emarginated ( Fig. 68 ); sternum IX 3x longer than aedeagus, arms lacking stout subapical setae, convergent posteriad, apices truncate, right arm slightly longer ( Figs. 69–71 ); syntergite bearing distinct transversal and medial sutures ( Fig. 69, 70 ); aedeagus with phallus subparallel-sided, basal projections of parameres fused medially, then projected basally, paramere slightly curved inwards, apex rounded ( Figs. 72, 74 ).

Etymology. The specific epithet takiyae is a noun in the genitive case, given after our colleague and friend, Professor Daniela Maeda Takiya, who was the first to find specimens of this species.
